The only purpose these chips CAN serve right now is eliminating the need to flash/reflash to change firmwares between xtreme and 0800. All of the other "features" are made up imo. No one knows $hit about how LIVE will be checking this, or even if it ever will, so saying anything about "disabling for LIVE" is complete B.S.
I honestly do not understand why anybody would pay for any of these chips until more progress is made, and/or we find out MS$ response.
On top of that, installing these $50 chips is harder than just flashing your own drive for free...
I am one for options, and if you like these chips, great, but I just don't personally see the point...
